In a study that sheds new light on the causes of Parkinson's disease, researchers report that brain cells in Parkinson's patients abandon their energy-producing machinery, the mitochondria. A shutdown in fuel can have devastating ...

It is said that each of us marches to the beat of a different drum, but new Stanford University research suggests that brain cells need to follow specific rhythms that must be kept for proper brain functioning. These rhythms ...

(PhysOrg.com) -- A chemical produced by common soil bacteria may kill neurons that produce dopamine, according to an article authored by University of Alabama researchers publishing Oct. 6. Dopamine neuron demise leads to ...

Scientists have identified a protein that appears not only to be central to the process that causes Parkinson's disease but could also play a role in muting the high from methamphetamine and other addictive drugs.

Neurons that produce the neurotransmitter dopamine are the cerebral cells that most commonly die-off in Parkinson's disease. The cells in the so-called substantia nigra, which contain the dark pigment neuromelanin, are affected. ...

Scientists at the California Institute of Technology have uncovered evidence of a primitive emotion-like behavior in the fruit fly, Drosophila melanogaster. Their findings, which may be relevant to the relationship betwee ...

Researchers are one step closer to understanding the neurobiology that allows people to successfully learn motivated behaviors by associating environmental cues with rewarding outcomes, according to a study published yesterday ...

New research with mice has provided some fascinating insight into how addictive drugs hijack reward signals and influence neural processes associated with learning and memory. The research, published by Cell Press in the ...

In a study that reveals the clearest picture to date of neuron death in Parkinson's disease, researchers at Columbia University Medical Center have found that a trio of culprits acting in concert is responsible for killing ...

(PhysOrg.com) -- Scientists have identified a protein that appears not only to be central to the process that causes Parkinson's disease but could also play a role in muting the high from methamphetamine and ...

In new research from Saint Louis University, investigators have found evidence that a toxin produced by the brain is responsible for the series of cellular events that lead to Parkinson's disease. The study, published in ...

The so-called reward center of the brain may need a new name, say scientists who have shown it responds to good and bad experiences. The finding, published in PLoS One, may help explain the "thrill" of thr ...

In a major breakthrough in the battle against Parkinson's disease, researchers at the University of Colorado School of Medicine have discovered a drug that stops the progression of the degenerative illness in mice and is ...
